Letters Patent No. 97,920, dated v.December 14, 1869;

The Schedule referredto in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, D. AIRWNG HoLooMmofI thecounty of Henry, and State of Iowa, .have invented a new 4and useful Improvement yin Fruit-Preserving Jars and I do hereby declare thattliefollowing is a full, clear, and exact description thereof, reference being had'l to the accompanying drawings, and toy the letters of vreference marked-thereon.

4The nature of myinventionconsists in providing'an economical air-tight fruit-preserving jar, which canv be easily and speedily :closed without the use of wax or other cement, audwhich ca nbe opened instantaneously without'injury to'any of its part-s, all of which can be usedas often as required, without alteration or re )aux 1Hretoford the great drawback to preselving `quam'v tities of fruit for household use' or shipment-has been the comparatively great expense of goodpreservingjars, and the disappointment eiqieriencedy as a. result of using cheap butworthless ones. Many efforts have.

Figure 3, an elevation of the jar, when covered and clamped. Figure4, a'plau of the same on the line z-s'.' Figure 5, a perspectiveview of the metal cap. Figure 6, the wlre fastener or yoke; A represents a.fi'uitjar, of glass or other suitable material, made with a wide flat surface orshoulderbed at B, to receive a ilat rubber ring, G, which is held in its place by an upright projection-forming the lmouth ofthe jar. l,

`D is a flanged capof thin metal, madeto fit as a cover for the mouth of the jar, with 'its flanged rim resting on the rubber ring O, and having' projections 01 supporting-lugs d o nits-'up'per surface, for the support and bearings of the wire fastener 'E, which is a piece of wire-bent into thes'hape of a ,yoke'fits extrern'ities tting tightly on the shoulder of the Jar, and pressing the metal cap .D .downward directly over the rubber ring C and shoulder of the jar, thereby avoiding thecommon difficulty of springing metallic caps by central pressure.

The cap D 'is japann'ed on its inner surface to prelvent its corroding.

. I preferthis method of closing, fruibjarsfby an iudependent wire fastener, whose pressure is brought to bea-r directly on the flange of the cap where it rests upon the rubber ring-to any fastener, whether attached to or'mdependent of the cap, whose pressure is brought to bear on the 'centreoftheca-p, for the reasonthatit is at the point of cont-act between the ange of the cap andthe rubber ring that pressure is essential, and not at the centre of the cap,'where it 4maylhave the eli'ect'ofv springing the 'flange and permitting airto pass between it and-the rubber.

And further, by means of an independent wire fastener, and the supporting-lugs ou the cap, the degree of pressure can be regulated by bending the wire more' or' less, and applied at the proper point, 'that is, inrmediately on the rubber ring, at the outer edge of the me al cover, in direct line withthe shoulder-bed of the jar; r The opera-tionof my invention is easy and simple. When the jar is filled, I place the rubberring on-the. flat surface B, put on, the cap D, and press the wire E with the thumbs into :its position betweenthe' projections or supporting-lugs d, reversing the operation when it is desired-to open .the jar.

'I claim the metal capD, provided with the projections or supporting-lugs dal, in combination with fast-' ener E, ring C, and jar A, the whole constructed and joperating substantially as and foi-'the purpose specilied. 1
